Impact of COVID-19 on oncological surgery of the upper gastrointestinal tract

The outbreak of the coronavirus disease 2019 (COVID-19) pandemic imposed limitations for elective surgery, impacting the associated hospital standards worldwide. As certain treatment windows must be adhered to in oncological surgery, the limited intensive care unit (ICU) capacity had to be critically distributed in order to do justice to both acutely ill and oncology patients. This manuscript summarizes the impact of COVID-19 on the management of oncological surgery of the upper gastrointestinal tract and particularly esophageal surgery in German medical centers.
